This project took me quite a while, before I started I didn't know a lot about electric bikes, and their components. I got a lot of info from this forum, so that's why I wanted to share this project
I decided, because of reasons, to convert my Ampler curt to an open source controlled Ampler curt, using a VESC. This all just fits into the space available, and it is able to read the pedal sensors, control the lights and turn the rear motor of course. I 3d printed a enclosed to match the original one.
For others interested in this project, this is the information I gathered
1. The motor in the Ampler is a motor made by AKM or Aikema, and generally referred to as a Q100C. Or the "Q100C CST 36V350W Rear Driving EBike Hub Motor - RPM : 201" you can find on Bmsbattery
2. The connecters used on the bike are Julet Mini connectors, I used the ones from this supplier
The parts I used for the conversion:
Arduino Pro Micro here
Flipsky mini fsecs here
Flipsky antispaak switch here
Replacement switch here
Small NPN transistor from Farnell
If people are interested I can provide some schematic, and a 3d print file and Arduino software
Now it is able to propel me to about 35kp/h , this varies a bit depending on the state of charge.
To turn on the lights, I have programmed the Arduino to turn them on when you move the pedals half a turn backwards after turning it on. Because the power switch is now a latching switch to control the antispaak switch I cannot use that to control it. The lights are power from the VESC 1A BEC (battery eliminator circuit). The Arduino controls the VESC using uart, I used this library to control it
